do you already have a VIN number? you sure thats the only change you made, and you didnt make some other change inadvertently? When you get a vin and have a MVPA (motor vehicle purchase agreement) it will have a breakdown of all charges so you will be able to see it then.
If you need to know before then and you dont have a vin, you will need to contact someone at tesla for a breakdown, since it appears you dont have one, or see it in your order page.
